ONE-LOK™ Series SLDE for Ductile Iron PipeSample Specification: Proper restraint of high pressure ductile iron pipelines shall consist of two wedge-action restraining glands used to secure the ductile iron plain-end pipe to a mechanical joint fitting or appurtenance. The restraining glands, wedge segments and break-off top actuating bolts shall be manufactured in accordance with ASTM A536, grade 65-45-12. Wedge segments shall be heat-treated to a minimum hardness of 370 BHN. The restraining glands shall incorporate the required extra-long t-head bolts/heavy hex nuts or threaded restraining rods/heavy hex nuts in accordance with AWWA/ANSI A21.11/C111. The restraining glands shall provide a minimum 2 to 1 factor of safety and be Sigma Tandem Series T-SLDE or approved equal.

1.) Clean fitting socket and pipe end. Lubricate gasket and pipe end with soapy water or approved pipe lubricant meeting AWWA C111. Install both Sigma One-Lok Model SLDE wedge –action restraining glands onto the end of the plain-end pipe so that the frontal lips of both glands face the pipe end. Follow the glands with a SigmaSeal™ gasket. Insert the pipe end into the socket and press the SigmaSeal™ gasket firmly and evenly into the gasket recess in the mechanical joint fitting cavity, while maintaining a straight joint throughout the installation.
2.) Slide the wedge gland closest to the pipe end up against the gasket with the frontal lip and insert the extra-long t-head bolts or threaded restraining rods with heavy hex nuts. Hand-tighten the t-head bolts or restraining rods evenly and make any necessary deflection after joint assembly but prior to tightening the bolts. Tighten the bolts in an alternate manner (star pattern) around the gland to the recommended torque (3 inch 45-60 ft-lbs., 4-24 inch 75-90 ft-lbs., 30-36 inch 100-120 ft-lbs. and 42-48 inch 120-150 ft-lbs). Maintain an even distance between the restraint gland and fitting face throughout the tightening of the bolts or restraining rods. The use of a torque-indicating wrench is recommended, keeping in mind that 30-48 inch assemblies may require repeated repetitions to ensure proper torque.
3.) Hand-tighten the break-off top actuating bolts until contact is made between each wedge insert and the pipe wall. Continue tightening the break-off bolts in an alternate manner (star pattern) until all of the break-off tops have been fractured. Slide the 2nd wedge restraint gland up and rotate accordingly to allow the t-head bolts or restraining rods to pass through the corresponding bolt holes, keeping a 1” space (dimension A in technical chart) between the two wedge-action restraint glands.
4.) Install an additional heavy hex nut on the backside of the second gland, hand-tighten and then snug each nut ½-1 turn with a wrench. Hand-tighten each break-off top actuating bolt until contact is made between the wedge insert and the pipe wall. Continue tightening the break-off bolts in an alternate manner (star pattern) until all of the break-off tops have been fractured.
